Effects of antidepressant treatment on corticotropin-induced cortisol responses in patients with melancholic depression.
To date, there appears to be no consensus of opinion as to whether the adrenal glands are hyperresponsive during depression and, if so, whether this a state-dependent phenomenon. We aimed to determine the effects of antidepressant treatment on ACTH-induced cortisol responses in patients with melancholic depression. Seven female patients with DSM-III-R major depressive disorder, non-psychotic, melancholic subtype, were evaluated using the following rating scales: the Hamilton Depression Rating Scale, the Montgomery-Asberg Depression Rating Scale and the Newcastle Endogenicity Scale. All subjects were then given an intravenous bolus dose (250 micrograms) of tetracosactrin, a potent stimulus of adrenocortical hormone secretion. Plasma levels of cortisol were measured at times 0, + 30, + 60, + 90, + 120 and + 180 min. Patients were then randomised to receive either 50 mg of sertraline or 20 mg of paroxetine (both of which are selective serotonin re-uptake inhibitors) and were re-tested while medication-free. Treatment resulted in a significant decrease in delta (the difference between the baseline values and the maximum increase post-ACTH administration) cortisol values of 1633.3 +/- 378.5 nmol/l vs. 595.1 +/- 207.7 nmol/l. Successful pharmacological treatment of major depressive disorder appears to be associated with a reduction in ACTH-induced cortisol release in drug-free patients.
